Measurements and electrical circuits
Note from June 29, 2020
Although we do not yet know how long the social distancing related to the Covid-19 pandemic will last, and regardless of the changes that had to be made in the evaluation of the June 2020 session in relation to what is provided for in this learning unit description, new learnig unit evaluation methods may still be adopted by the teachers; details of these methods have been - or will be - communicated to the students by the teachers, as soon as possible.

Main themes
This course deals with electrical circuits and measurement techniques, serving as basis of the cursus in Electrical Engineering. It is also highly coupled with the project LELEC1101.
Aims

At the end of this learning unit, the student is able to :

1 Contribution of the course to the program objectives (N°)
Axis 1 (1.1, 1.2, 1.3), Axis 6 (6.1)
Specific learning outcomes of the course
At the end of the course, the student will be able to :
  • Analyze and understand electrical circuits made of resistors, capacitors, (coupled) inductors, ideal operational amplifiers and sources
  • Calculate voltages and currents in AC steady-state (phasors) and in transient state (Laplace transform)
  • Represent the transfer function of an electrical circuit (Bode analysis) and identify its function (filtering, integration, amplification, etc.)
  • Identify the different two-port networks within a complex circuit, calculate the individual characteristics and derive the overall characteristics (serie or parallel connections)
  • Calculate the consumption of an electrical circuit (active and reactive power)
  • Solve polyphase circuits (in particular, three-phase circuits)
  • Understand and design typical measurement circuits: bridge circuits (sensitivity, accuracy) and instrumentation amplifier
  • Understand the concepts of sensitivity, accuracy and measurement errors (including error combinations) in the field of electrical measurements.
 

The contribution of this Teaching Unit to the development and command of the skills and learning outcomes of the programme(s) can be accessed at the end of this sheet, in the section entitled “Programmes/courses offering this Teaching Unit”.
Content
  • Resistive circuits and operational amplifiers
  • AC steady-state analysis: phasors, variable-frequency analysis (Bode)
  • Filter two-port-networks
  • Magnetically-coupled networks
  • Time-domain analysis and Laplace transform
  • Steady-state power analysis
  • Polyphase circuits
  • Measurement techniques
Teaching methods
Teaching is organized in weelkly courses and supervized exercise sessions. A mid-semester interrogation is organized around the 5th week about AC steady-state analysis.
Evaluation methods
Students are evaluated individually in a written exam, on the basis of the learning outcomes mentioned above. The exam essentially focuses on solving exercises and/or answering theoretical problems (no book/notes are allowed, only a form provided with the questions can be used).
Other information
The courses LFSAB1201 (Physics 1) and LFSA1502 (Project 2) are prerequisites.
